Fixes an error message and docstrings that no longer match the code.

  • ActiveSubspace error message and tutorial 07: .add_emergent_property() -> .add_property(), .find_active() -> .find_directions(). Tutorial 13: get_scores_on_observed_data -> get_scores.
  • TransformerEmbedding examples crashed (feature_space_dim not divisible by the default 12 heads); 64/128 -> 48/96.
  • fit_gmm: num_samples default is 1000 * d * num_components, not 10_000.
  • Args sections: rename or remove 15 entries that did not match the function signature (e.g. CNNEmbedding num_cnn_layers -> num_conv_layers).

Review comments at @sbi/neural_nets/embedding_nets/cnn.py:
- Line 126: Update the `pool_kernel_size` description in `CNNEmbedding` to cover
the selected `MaxPool1d` or `MaxPool2d` layer, matching the supported input
dimensions.

Review comments at @sbi/samplers/vi/vi_quality_control.py:
- Line 105: Update the documentation for q to describe it as the proposal
distribution approximating the target density proportional to
exp(potential_fn(theta)), since potential_fn is a log potential.
Walkthrough

This PR updates sensitivity-analysis guidance, Transformer examples, and API docstrings across the repository. It corrects documented method and parameter names, removes obsolete argument descriptions, and updates the documented fit_gmm sample-count formula. Executable behavior and public signatures are unchanged.

Changes: Documentation and example updates

Layer / File(s) Summary
Update sensitivity and diagnostic guidance
sbi/analysis/sensitivity_analysis.py, docs/advanced_tutorials/07_sensitivity_analysis.ipynb, docs/advanced_tutorials/13_diagnostics_lc2st.ipynb
The error guidance and sensitivity-analysis tutorial use current method names. The L-C2ST-NF overview names get_scores as an evaluation method that does not require theta_o.
Correct embedding documentation and examples
sbi/neural_nets/embedding_nets/transformer.py, sbi/neural_nets/embedding_nets/cnn.py, sbi/neural_nets/embedding_nets/lru.py
The Transformer examples use feature_space_dim=48 and feature_space_dim=96. Embedding docstrings use updated parameter names, and the Transformer forward docstring no longer lists output_attentions.
Align API parameter documentation
sbi/analysis/plot.py, sbi/inference/posteriors/ensemble_posterior.py, sbi/inference/trainers/base.py, sbi/neural_nets/estimators/*, sbi/neural_nets/net_builders/categorial.py, sbi/samplers/vi/vi_quality_control.py, sbi/utils/conditional_density_utils.py, sbi/utils/user_input_checks.py, sbi/utils/vector_field_utils.py
Docstrings use updated parameter names and descriptions. The fit_gmm documentation states that omitted num_samples uses 1000 * d * num_components, matching the existing implementation.

Merge Risk: Minimal · up to f2b84

The PR introduces no remaining merge-blocking risk; the stale tutorial API references are fixed, while the retained documentation improvements are pre-existing.

Explanation

The title "docs: fix stale method names, crashing examples and a default in docstrings" matches the main change. The PR fixes stale method names in an error message, docs, and tutorials, corrects two TransformerEmbedding examples that crashed, and fixes a fit_gmm default in docstrings. The title is specific and accurate. It lists three kinds of fixes, which is slightly long at 75 characters, but it is clear.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 8 functions across 13 files. (2 skipped: 2 unsupported.)

Full details: Description check

Explanation

The description states what the PR fixes: an error message and docstrings that no longer match the code. It lists each change by file or symbol, including the ActiveSubspace renames, the TransformerEmbedding dimension change, the fit_gmm default, and the Args section corrections. It does not follow the template. It has no 'Does this close any issues?' section, no 'Anything else we should know?' section, and no checklist. The checklist items (tests, pytest, pre-commit, pyright, docstring style) are not addressed. It also does not say whether the AI-assistance disclosure applies. The objectives note that tutorial notebooks 07 and 13 still contain old names, but the raw summary shows those notebooks were changed. The description and the code changes disagree on this point, and the description does not reflect the final state of the PR.

Resolution

Add the template sections that are missing: 'Does this close any issues?' (write 'None' if no issue applies), and 'Anything else we should know?'. Complete the checklist, or state which items were run and which were not. Include the test results for the TransformerEmbedding examples and the ActiveSubspace error message. Include a note on AI-assistance use if it applied. Resolve the conflict between the description and the change summary about tutorial notebooks 07 and 13. The description says those notebooks are not changed, but the summary says they are. Update the description to match the final diff.
